The nature of my invention consists- First, in the use of vertical grooves in'the shoe, and

indicate corresponding parts in the in tenoned board fitting in the same, in different posis tions, for opening and closing the trough in the shoe.

Secondly, in devices for holding or hanging the up-- per end of the shoe to allow of more or less lateral motion of the same.

Thirdly, in devices for allowing of the attachment of the short shaker-rod to diflerent places on the shoe,

so that the power may be applied to shake centrally or bodily, shown at r, fig. 5. Y I

Fonrthly, in devices for operating a knocker to keep the screens clean. i

Fifthly, theuse of a hollow open shaft for whcel and pinion at outside of fan-case, to permit the long rod to be more centrally attached to the pinion or crankwheels, so as to give a shorter shake of the shoe than has been heretofore possible;

Sixthly, in devices for giving increased motion to a shoeoi'a grain-cleaner without increasing the revolutions of theian-shaft, consisting of an extra or supple mental wheel or disk.

A A in my drawingsrepresent the uprightframe of I a fanning-mill supporting the cross-pieces B B and the sides (1 and drum-D.

Secured to the Cl'OSS'rPlGCG B are the boards E provided on their inner surface with grooves, 12 e, in which the board F slides, and securely held together by the cross-piece G over the top, and under the bottom of which the grooves c 0 run, coming together in front at an angle so that the board F has more slant in the upper groove than in the lower one.

' Pivoted at its top to the front of the hopper E, at a, is the swing-hoard H, which is adjusted by a cam-lever, F, and spur, pivoted at its front side, as shown in fig.2.

I, figs. 1 and 2, is a vibrating. shoe hung at the rear by straps b, and in front on hooks c and slotted plate 0'.

The sides of the shoe I are provided with different shoe to its front end, the grooves g g and h running to the end of the part I in the grooves f slides the screen J, which is generally a fine-meshed one, the groove It holds the-chess-board M, and the other grooves are used as they are needed for'difi'erentkinds of grain and seeds. The screen N issupported at its rear end by pins on its sides near its upper end catching in ra'tchets, its front or lower end resting onits shown in fig. 2. The screen J is held in position by a hookorany other convenient device, and the other screens and board are held by a rod passing "through them at one edge and through staples on'the inside of the shoe. 7

At the upper or inner end of part I of the shoe I is placed a sloping bottom trough, 1, across the entire width of the"shoe, its lower end connecting at the side of the shoe with the spout 1*,as shown in fig. 2, and directly under the lower end of screen J, so that the small seeds, chess, and other impurities falling through the screen J upon the upper grain-board are shaken into the trough I and run from it into the spout I and fall into the chess-box O.

The rear-side board of the trough i figs. 9 and 10, is made adjustable by having a square teuon, (1?, on its the piece (I with its sides vertical, when the screw J is used, thus forming a trough also for holding it in a nearly horizontal position, thus shutting up the box, and making a continuous grain-board to be used when cleaning small grain and seeds when screen J is not used.

Inside the drmn its hearings on standards A A, and provided with arms P to which wings Q, are attached. At its ceuterit is provided with a circular rim, R, which acts asa guide to the currents of air coming in on each side of the the air to pass out in an even continuous blast.

At one side of the mill, inside of the drum D, is situated a gear-wheel, S, giving motion to the shaft sets of grooves, f,.rnnning the entire length of the bent portions of 1) inside the shoe of a rod 11, as.

ends, which fits into vertical grooves, (1 for holding D rotates the fan, its shaft having drum, partially changing their directiomand causing o and fan-wings, pulley, and shoe, by means of the pinion T and operated by the handle U.

At the opposite side, just outside of the bearings, a gear, belt, or friction-wheel, V V V, is placed, as shown at V in figs. 1, 3, 4, and 7, for giving motion to the shoe through the rods P and P, and bell-crank P being rigidly attached to the fan -shaft, as shown at fig. 4, at A, and provided with an open shaft, as shown at A, fig. 4, to allow the bent end of the long rod P to pass into the holes 0 in the wheel'Vuearer its center than would be possible with a solid shaft, thus producing a smaller or lighter shake or vibration of the shoe than is otherwise attainable as ordinarily constructed.

Immediately above this wheel V is placed a disk or wheel, V, which may be run or rotated upon its axis by a cog-gear, flictiompulley, by a, belt, or otherwise. This pulley-wheel V 2 is fixed on a shaft, e, held in bearings 2 parallel with the fan-shaft; these hearings may be raised or lowered at pleasure by means of a bolt, 6', which holds it in position, sliding up and down in a slot, e in the post A, fig. 4, thus allowing it to be thrown in or out of mesh, and also allowing pinions of difiercnt sizes to be used'to still further increase or diminish'its motions relatively to the wheel V. This pulley or wheel has holes in its face, as shown ate, to receive one end of the long rod when taken out of wheel V to increase the number of vibrations of the shoe without increasing the revolutions of the ian-shaft; the number of vibrations may thus be increased to almost any extent.

Attached to the rod P is a wire, W, which has two eyes or points of attachment, as in figpl at c. To this rod W the upper end of' rod X hooks, as shown at c, fig. 1; this rod X hooks into the bent part at of the knocking-rod p, as shown in fig. l at ll, for shaking the same by means of the vertical motion of rod X given to it by the-long rod P. When the rod P is attached to the wheel V the rod X is attached to the upper eye of rod W, and when the rod P is attached to the wheel V the rod Xiis attached to the lower eye of rod W, thus making the action of rodX always the same on rod m. The rod in is provided with holes at different distances from the end, to allow of different degrees of motion being given to rod 1, as may be desired.

At 0' is a large chess-box, opened or closed at the rear by any convenient device.

The sliding-doors over the wind-holes in the drum are provided with cleats which rest on bars on the machine, and are held in any position desired by points in said cleats dropping or projecting into the bars, thus preventing the accidental displacement of the same.

To clean wheat, pour it into the hopper E on the hopper-bottom F, on which, by reason of its being nearly the same width of the shoe,v the grain is spread out, and delivered in a thin, wide, even sheet on to the screens, the rear opening being adjusted and :grooved plate t in the side of the hopper E, and to feed faster than the utmost swinging of the board H will allow, it is only necessary to draw the board out in the grooves.

The screen J is so placed that when the grain falls upon it, most of the chess, cockle, and other impurities pass through the screen J and fall upon the upper grain-board n, and are carried into the through I from which they are shaken through the spout 1 into the chess-box C. The wheat passes on to the coarse screens which take out the coarse large particles, and allow the wheat to fall on to the chess-board. This board is provided with several holes, by means of which it may be adjusted nearer to or further from the rear end of the shoe, so that, as the grain falls from the board to the screen N,'the wind strikes it for the first time, and blows out most of the remaining im purities.

The grain has now fallen on to the lowest screen N, which is constantly shaken laterally by the shoe, and vertically by the rod 12. If any impurities still remain they are sifted and jolted through the meshes of the screen into the chess-box, while the pure wheat is carried over the screen N and lower grain-board K on to thefioor or into a box placed to receive it.

To clean small seeds, the screen J is taken out, the adjustable part of the trough I placed horizontal, thus formiu g a continuous upper grain-board, and the proper screens placed in their respective places by means of the devices described Very superior results are thus obtained.

Having thus described my invention,

What I claim therein as new and useful, and desire to secure by Letters Patent, is-

1. The trough I and screen J, in combination with the tenoned piece d and spout I, when used together for the purposes and in the manner described.

2. The open or slotted shafts A when used for the purposes and in the manner set forth.

3. The double eye r and rod P, in combination with the book 0 and plate 0*, when used together for the purposes and in the manner set forth.

4. The rods W and X, in combination with rod m and 1:, when attached and used together, for the purposes and in the manner set forth.

5. The book 0 and adjustable slotted plate 0, or their equivalents, when used for the purposes set forth.

6. Providing a pinion V, or its equivalent, with an: adjustable journal-box or hearing, when used for the purpose of varying and regulating the speed of motion of the shoe in a grain or seed-cleaner, substantially in the manner and for the purposes herein set forth. Witnesses: HARRISON OGBORN.
